Bloomberg News reports the European Union is preparing to intensify its investigation into Meta's platform design under the Digital Services Act, focusing on addictive features — a probe that could force structural changes to Meta's core engagement-driven model across Facebook and Instagram. Meta generated $201B in revenue in FY2025 (+22% YoY) with 30.1% net margins, meaning any forced redesign of recommendation algorithms or feed mechanics in Europe would directly threaten the ad revenue flywheel.

The second-order risk is that a DSA enforcement action could set a precedent for other jurisdictions and pressure Meta to make global product changes rather than run fragmented experiences. Key things to watch: the scope of the probe (design mandates vs. fines), timeline to enforcement action, and whether other major platforms get swept into similar scrutiny.
